9a56e04261 Fix microtime() to sanely handle calls before the clocks have been 
initialized. This is the DC21285 version of the IOMD fix for PR7357.

a1cca18262 Implementing bus_space_barrier(9)::isa_bs_barrier() with panic(9) 
does in fact get you a barrier, but it's unnecessarily drastic.
Fixes kern/7431 "SHARKs with a serial console and com.c 1.59.2.1 won't boot".

902004cefc Don't try and calculate the time in microtime() unless cpu_initclocks() 
has already been called and thus we know the values the timers are using.
This also ensures that clock_sc will always be valid when we try and use
it to read the timer registers.

12f5abbcee A few things:

ea8db6d88d Fix the vunmapbuf() problem, by zeroing out the PTEs before freeing the VA

93768384ee Fix a bug in pmap_collect_pv(), even though nobody currently uses it: 
When we put a page on the collection list, we must subtract NPVPPG from the
total free count: one for each pv_entry that's free in that page, and one for
each free pv_entry in other pages that we're going to eat by moving the ones
in the page being collected.

32295b2dac Further cleanup: 
pmap_find_pv(), pmap_clean_page() and pmap_remove_all() are only called on
managed pages, after VM initialization.  Panic if this invariant is violated.
Also, panic if we try to enter a PT page through pmap_enter(), rather than
silently patching it up.
pmap_initialized is now #ifdef DIAGNOSTIC.

9c6b797796 Changes for modified pmap_enter() API: 
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just
  because'.
* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
  avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot.  Also, DO NOT use
  pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
  access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
  access_type = 0.  This should probably be revisited.

e84fe91c51 Take advantage of the new `access_type' for pmap_enter(), and always do R/M 
emulation of managed pages.  This required the following `interesting' changes:
* File system buffers must be entered with an access type of
  VM_PROT_READ|VM_PROT_WRITE, so that the pages will be accessible immediately.
  Otherwise we would have to teach pagemove() to update the R/M information.
  Since they're never eligible for paging, the latter is overkill.
* We must insure that pages allocated before the pmap is completely set up
  (that is, pages allocated early by the VM system) are not eligible for R/M
  emulation, since the memory needed for this isn't available.  We do this by
  allocating the pmap's internal memory with uvm_pageboot_alloc().  This also
  fixes an absolutely horrible hack where the pmap only worked because page 0
  happened to be mapped.
  to be mapped.
Also:
* Push the wired page counting into the p->v list maintenance functions.  This
  avoids code duplication, and fixes some cases where we were confused about
  which pages to do it with.
* Fix lots of problems associated with pmap_nightmare() (and rename it to
  pmap_vac_me_harder()).
* Since the early pages are no longer considered `managed', just make
  pmap_*_pv() panic if !pmap_initialized.

destination pages.

and thus this needs setting up first.

900bbc08fc Soft interrupt dispatching now uses the soft_interrupts variable along 
with the spl_smasks array and the current_spl_level variable to work
out which soft interrupts are pending.
This means that soft interrupts are now separated from the hardware
interrupts so a full 32 hardware and 32 software interrupts can now be
supported.
Implement clearsoftintr() function.
Define several macros to make the soft interrupt dispatching code cleaner.
